Looking for laminated glass+polishing wheels+EVA+PVB

Detail Information:
I am actually looking for a reliable supplier of PVB, EVA,Polishing wheels and etc, but although my company is based in Belgium (Europe) my principal market is Iran. My team speaks, reads and writes Farsi. The most important criteria are:
- good quality of the PVB;
- the Chinese company should signed a distributor agreement with me;
Thanks for your support.
